2 Myths Vs Facts See Talking Point document in your packet

3 Vaccines does not cause the disease Vaccines contain either dead or live proteins called antigens. Live attenuated vaccines have living microbes that are weakened could make someone sick and should not be given to people with certain conditions. include live influenza, measles, mumps, and rubella. Inactivated or dead vaccines cannot make you sick. If someone is exposed to the infection before the vaccine has triggered an immune response, the person could come down with the illness after

4 Vaccines do not cause Autism The science does not support a link between vaccines and any developmental delays, including autism. The March of Dimes, AAP, Institute of Medicine, FDA, CDC, NIH and World Health Organization all confirm the safety of vaccines. The original article reporting a link between the measles, mumps and rubella (MMR) vaccine and autism was fraudulent, and the author later lost his medical license.

5 Vaccines are very safe. Each vaccine is tested rigorously in clinical trials before it can be approved by the Food and Drug Administration. Once it is approved for use in humans, the research is reviewed by the Advisory Committee on Immunization Practices (ACIP), a group of experts who advise the CDC on immunizations. This group spends months or years reviewing the data before making recommendations

6 Vaccine side effects are usually mild and temporary. Most side effects are mild or moderate, meaning they do not affect daily activities. Severe side effects are extremely rare and are less severe than the complications from getting the disease.

7 The main side effects of being vaccinated are: Soreness at the site of injection Headache and upper respiratory infection Fever, joint pain, sore throat Nausea, vomiting, diarrhea; more common in childhood vaccines

8 Vaccines severe reactions are rare Any severe adverse reaction should be reported to the Vaccine Adverse Event Report System (VAERS) at or by calling These reactions are monitored and reviewed regularly by the CDC Immunization Safety Office and the ACIP.

9 Vaccines and Mercury Many medications and vaccines contain preservatives to prolong shelf life. All vaccines recommended for pregnant women are available without mercury. Thimerosal, a mercury-based preservative, was removed from childhood vaccines in still used in the multi-dose vial of the adult influenza vaccine. None of the whooping cough vaccines (Tdap and DTaP) currently used in the United States contain thimerosal.

10 Mercury Researchers have conducted extensive research and have found no link between the mercury previously used in vaccines and the risk of side effects, especially in pregnant women.

12 ACIP: Guidance for Vaccine Recommendations in Pregnant and Breastfeeding Women General Recommendations for use Specific Travel vaccine information

13 Vaccines in Pregnancy Yes Influenza: Inactivated-Dead virus recommended each year Pertussis: Tdap in each pregnancy weeks Maybe No Hepatits A, Hepatitis B HPV, MMR, Live influenza virus, Varicella

14 Recommendation for Routine Vaccine Use in Pregnant Women Influenza AAFP, AAP, ACNM, ACOG, AMA, ANA, AOA, APhA, AWHONN, March of Dimes, and CDC urge vaccinating pregnant and postpartum patients against seasonal influenza. Tdap ACOG & ACNM

15 Influenza virus that causes influenza is transmitted through aerosols, large droplets, or direct contact with secretions drier the air, the longer the viral particles live The contagious period lasts from 1 to 2 days before and to up to 5 days after symptoms begin. Viral particles can live on non-porous surfaces, such as doorknobs and telephones, for up to 24 hours, and on paper surfaces, such as tissues, cloth, or paper, for up to 15 minutes. WHO, interventions for pandemic influenza, international measures. Emerg Infect Dis 2006;12:81 7.

16 Influenza and pregnancy Pregnant women who acquire the flu are 4x more likely to develop complications Fetuses exposed to flu-like illnesses are increased risk for Congenital malformations, miscarriage and stillbirth altered brain development including Parkinson s, schizophrenia Hayes, 2008, JMWH

17 Influenza Vaccine Vaccine is produced based on estimates of next year s outbreak Vaccine efficacy depends on the age and immunocompetence of the person receiving the vaccine The accuracy of the vaccine Timing of administration

18 Immuongenicity It takes a few weeks for the vaccine to produce antibodies The person is not protected for a few weeks after the vaccine A person can be exposed to the virus near the time of vaccination and still come down with the disease.

19 Rasmussen, Seminars in Fet & Neo Med, 19(3) 2014, p Tamma, Am J of Ob and Gyn. 201 (6), 2009, Steinhoff, N Engl J Med 2010; 362: A Naleway et al. Epidemiol Rev 2006;28: Yeager et al.. Am J Perinatol 1999;16: Studies have demonstrated the inactivated influenza vaccine to be safe in pregnancy, with no increased risk of maternal complications or adverse fetal outcomes. The benefit far outweighs the risk in protecting the fetus and newborn

20 Pertussis ( whooping cough ) Pertussis is still on the rise worldwide Pertussis is a highly contagious bacterial disease

21 Pertussis Coughing fits due to pertussis infection usually last from 1 to 6 weeks, but can go on for up to 10 weeks or more. Pertussis can cause serious illness in children and adults Newborns and infants are especially hard hit by this disease. Infants less than 12 months are at highest risk for severe disease and death. CDC

22 CDC.gov Cases of Pertussis in US: Week of August 9, 2014 August 30 week 203 Previous 52 weeks average 750/week Cumulative this year 16, : 25,000 (final number to be released soon) 2012: 48,277 including 20 pertussis-related deaths, mostly in infants <3mo 2010: 20,550

23

24 Dtap vs Tdap Infants begin their pertussis immunization series (Diphtheria-Tetanus-Acellular Pertussis or DTaP ) at two months, maximum protection is not achieved until the primary series is completed. Adolescents and adults are recommended to be immunized with a booster dose - Tdap ANYTIME Approved for those over age 65 In June 2009, CDC eliminated the minimum interval

25 CDC 2008 Recommendation for Tdap Vaccination in Post-Partum Period For women who have not received Tdap previously (including women who are breastfeeding), Tdap is recommended as soon as feasible in the immediate postpartum period to protect the women from pertussis and reduce the risk for exposing their infants to pertussis. The postpartum Tdap should be administered before discharge from the hospital or birthing center. If Tdap cannot be administered at or before discharge, the dose should be administered as soon as feasible thereafter. Elevated levels of pertussis antibodies in the mother are likely within 1--2 weeks after vaccination.

26 Definition of Cocooning Immunization of family members & close contacts of the newborn

27 Pertussis in infants Family members/care providers are the main source of pertussis to infants 75%-83% of infant pertussis cases were caused by an infected household member. Parents and siblings are the most common source, 55% of cases in infants linked to an infected parent. Bisgard KM, et al. Pediatr Infect Dis J 2004; 23(11): Wendelboe AM, et al Pediatr Infect Dis J 2007; 26(4):

28 Healthy People 2010 objective Counties that reached the goal of 90% vaccination coverage 94% for hepatitis B vaccine, 93 % for polio vaccine, 86% for MMR vaccine, 71% Hib vaccine, 50 percent for varicella vaccine, 8 % for DTaP/DTP vaccines, County-Level Trends in Vaccination Coverage Among Children Aged Months--United States, " MMWR Surveillance Summaries (04/29/11) Vol. 60, No. 4, P. 1

29 Tdap 2005 vaccine approved for adults 2006, the Advisory Committee on Immunization Practices recommended Tdap vaccination of All health care workers All caregivers of infants aged <1 year ( cocooning ) to prevent pertussis related complications and deaths.

30 Tdap in every pregnancy October 2012, ACIP recommended a dose of Tdap during each pregnancy, irrespective of the patient s prior history of receiving Tdap

31 Tdap preferably during the third trimester weeks Providers are encouraged to report administration of Tdap to a pregnant woman, regardless of trimester, to the appropriate manufacturer s pregnancy registry : Adacel to sanofi pasteur, telephone Boostrix to GlaxoSmithKline Biologicals, telephone

32 GA House Bill 249 Requires all new post partum women receive information on pertussis disease and the availability of a vaccine to protect against such disease Effective

33 Vaccine in pregnancy benefit outweighs the risk Hepatitis A The safety of hepatitis A vaccination during pregnancy has not been determined; however, because hepatitis A vaccine is produced from inactivated [hepatitis A virus], the theoretical risk to the developing fetus is expected to be low. The risk associated with vaccination should be weighed against the risk for hepatitis A in pregnant women who may be at high risk for exposure to hepatitis A virus.

34 Vaccines recommended in Hepatitis B some circumstances Pregnancy is not a contraindication to vaccination. Pregnant women who are identified as being at risk for HBV infection during pregnancy (e.g., having more than one sex partner during the previous 6 months, been evaluated or treated for an STD, recent or current injection drug use, or having had an HBsAg-positive sex partner) should be vaccinated.

35 Vaccines recommended in some circumstances Polio - inactivated Although no adverse effects of IPV have been documented among pregnant women or their fetuses, vaccination of pregnant women should be avoided on theoretical grounds. However, if a pregnant woman is at increased risk for infection and requires immediate protection against polio, IPV can be administered in accordance with the recommended schedules for adults.

36 Vaccines with inadequate data in pregnancy Meningococcal MCV4 Pneumococcal Conjugate PCV4, 7 or 13 For children Pneumococcal Polysaccharide PPSV23 All adults 65 years of age and older. Anyone 2-64 who has certain medical problems

37 Vaccines contraindicated in pregnant women HPV Live influenza (nasal) MMR Varicella Zoster

38 Pneumococcal Vaccination The Joint Commission, the Hospitals Quality Alliance (HQA) and the Centers for Medicare and Medicaid Services (CMS), recommends pneumococcal vaccination for persons at high risk for developing pneumonia.

39 Adult triage for PPSV vaccine Anyone 2-64 who has a long-term health problem heart disease, lung disease, sickle cell disease, diabetes, alcoholism, cirrhosis, leaks of cerebrospinal fluid or cochlear implant. Immunosuppressed Hodgkin s disease; lymphoma or leukemia; kidney failure; multiple myeloma; nephrotic syndrome; HIV infection or AIDS; damaged spleen, or no spleen; organ transplant. long-term steroids, certain cancer drugs, radiation therapy. smoker or has asthma

40 Each woman who is vaccinated should receive the Vaccine Information Sheet approved by the CDC. These information sheets can be downloaded from either or

41 Post Partum Vaccines All Adult recommended vaccines, except live virus (at risk of transmitting to newborn) CDC and CMS recommend every hospital have standing orders to deliver influenza and pneumococcal vaccinations as recommended by ACIP and the Task Force on Community Preventive Services.

42 SHARE SHARE the tailored reasons why the recommended vaccine is right for the patient given their age & health status, HIGHLIGHT positive experiences with vaccines (personal or in your practice), as appropriate, to reinforce the benefits and strengthen confidence in vaccination. ADDRESS patient questions and any concerns about the vaccine, including side effects, safety, and vaccine effectiveness in plain and understandable language.

43 Practice Standards for All Healthcare Professionals 1. Assess 2. Strongly recommend 3. Administer or refer 4. Document

44 ASSESS immunization status of all your patients at every clinical encounter Stay informed. Get the latest CDC recommendations for immunization of adults. Implement protocols and policies. Ensure that patients' vaccine needs are routinely reviewed and patients get reminders about vaccines they need.

45 Strongly RECOMMEND vaccines that patients need Share tailored reasons why vaccination is right for the patient. Highlight positive experiences with vaccination. Address patient questions and concerns. Remind patients that vaccines protect them and their loved ones against a number of common and serious diseases. Explain the potential costs of getting sick.

46 ADMINISTER needed vaccines or REFER your patients to a vaccination provider. Offer the vaccines you stock. Refer patients to providers in the area that offer vaccines that you don't stock.

47 DOCUMENT vaccines received by your patients. Participate in your state's immunization registry. Help your office, your patients, and your patients' other providers know which vaccines your patients have had. Follow up. Confirm that patients received recommended vaccines that you referred them to get from other immunization providers.
